Airtac MTF Mini Cylinder MTF32X80CA
The AirTAC Airtac MTF Mini Cylinder MTF32X80CA is a genuine single acting, pull (spring return) JIS-standard round-body mini air cylinder with a Ø32mm bore and 80mm stroke, 1/4" air ports and a SUS304 stainless-steel barrel for mildly corrosive environments. For the same bore and stroke it is shorter than an ISO 6432 cylinder, saving mounting space.

About the Airtac MTF Mini Cylinder MTF32X80CA
Delivering 266.8 N of net pull force at 0.5 MPa, this 32 mm bore pneumatic mini cylinder is engineered for spring-open, air-close operations. The internal spring constantly pushes the 12 mm rod to the extended position, while supplying air to the 1/4" port retracts it. Because it lacks a -S suffix, this specific SKU cannot accept CMSG, DMSG, or EMSG magnetic switches.
Built with a SUS304 stainless steel round barrel and riveted aluminium covers, the JIS-standard body is purposefully shorter than an equivalent ISO 6432 unit, saving valuable machine space. It relies on fixed TPU bumper pads for end-of-stroke deceleration rather than an adjustable cushion. For sizing reference, its effective vertical lift capacity is roughly 13.6 kg when applying a 2:1 safety margin to the 0.5 MPa output.

Where the Airtac MTF Mini Cylinder MTF32X80CA Is Used
Tension Mechanisms
Provides 266.8 N of net pull at 0.5 MPa to draw back tensioned belts or cables, safely releasing the tension when compressed air is cut.
Fail-Safe Open Valves
Holds process valves open via spring force; air pressure pulls the rod inward to close the valve, ensuring a secure extended state during power loss.
Retracting Stops
Pulls physical package stops out of the conveyor path on command, with the spring automatically pushing the stop back into blocking position at rest.
Is the Airtac MTF Mini Cylinder MTF32X80CA the Right Cylinder?
When selecting this model, size both ways against your tensioning requirements: the smaller MTF25 provides 153.6 N at 0.5 MPa, while the larger MTF40 yields 434.8 N at 0.5 MPa. This 32 mm bore hits a solid middle ground for pulling mechanisms that must fail safely to the extended position upon air loss. A minimum operating pressure of 0.2 MPa is required to overcome the internal spring. The integrated CA rear pivot cover suits trunnion-style articulation, and you must upgrade to an -S variant if position sensing is needed.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/CM) & mount (LB/FA/SDB/TC)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.2 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MTF Mini Cylinder MTF32X80CA FAQ
This single-acting pull cylinder generates 266.8 N of net pull force at 0.5 MPa and 405 N at 0.7 MPa. It requires a minimum air pressure of 0.2 MPa to overcome the return spring and retract the rod.
The spring constantly extends the rod, meaning the cylinder fails to the extended position on air loss rather than holding a mid-stroke load. Additionally, this non-S SKU lacks a magnet and cannot mount position sensors.
